Résumé

This paper presents the experimental measurements carried out during flow boiling heat transfer of R134a on a Carbon/Carbon surface. This material appears to be a viable option for future thermal management devices because it exploits interesting properties having a low density and a relatively high thermal conductivity as compared to copper; moreover, it is already used in many industrial applications where it is shaped in various forms even complex. The sample was tested in a new experimental facility especially designed to study the flow boiling heat transfer process on innovative materials and enhanced micro- and nano-structured surfaces. The tests were run at constant saturation temperature of 30°C and heat flux of 50 kW m-2, by varying the refrigerant mass velocity from 50 to 200 kg m-2 s-1.
